Supposedly had to collect the key card from the security for check in, but had a bit of language barrier with the security guard on duty whom then directed me to a kind resident, who spoke to NUi on the phone for me and personally showed me to the room.
Other than that, the room was big, clean and cozy, though it was a little bit far from the mrt station and a little inconvenient to walk. 7-11 right at your doorstep. Nestled in a pretty quiet neighbourhood outside of town area. Great stay, would recommend to solo travellers.
